In the scene where Sam, Freddie, and Carly are in the in the conference room at Dakka, Sam has a sandwich and has taken a bite of it. Before Sam takes another bite to begin choking, we see the sandwich change position in two different shots. One shot as camera in front of Sam, the sandwich bite is facing out and cut to side shot, the sandwich bite is facing toward Sam.
During the webacast in which the girls poke fun at the Techfoots, there is a dialog mismatch between the live broadcast and the clips that Spencer plays back for the company agents. For instance, Freddie demonstrates the faulty WiFi access point in the shoes and says, "It wipes out your entire hard drive!" to which Sam jokingly replies, "Isn't that great?", but when Spencer plays that portion of the video, Carly is heard to say "like a magic eraser" before Sam's reply. The same thing happens when she demonstrates how one can easily tear through the shoe when it is dipped in water; the first time, she says "Shove your toes through the front like this," and the second time, she says "Shove your toes through the front like this to cool 'em off."
Spencer falls asleep on a Seattle city bus where he wakes up in Vancouver, Canada. This would not be feasible as he took a city bus. For Spencer to have arrived from Vancouver from Seattle by bus, he would have to have booked a ticket to take a long distance bus such as Greyhound and he would have to show a form of ID such as a passport to border control.
The squeaking does not match with either Carly or Freddie's feet movements
When beginning the web show Carly and Sam jog in place with the techfoot shoes making them squeak. But Carly and Sam are on a rug, the shoes shouldn't squeak when on a rug.
